Definitions
- the invention relates to a device for applying a protective layer to the weld or solder seam of can bodies with an application roller serving to apply a coating mass within an area covering the seam on the inside of the can body, the two lateral, for supporting the can body on the application roller serving supporting edges and a middle part located between the supporting edges and used to carry and apply the coating mass, which extends from the center of the roll to each of the two roll sides to the last kink or turning point of one representing the roll profile of the application roll and from one to the other roll side peripheral Jacket line extends before the point or area start on the jacket line or, in the absence of such a kink or inflection point, extends to the point or area start in which the can body comes to rest on the support edge assigned to the relevant roll side.
- Devices of this type are known for example from CH-PS 624,591, DE-PS 31 34 968 and US-PS 4,361,113.
- these and also all other known devices of the type mentioned at the outset were not yet suitable for providing the weld seams of can bodies with an optimal coating of paint in every respect .
- newer devices of this type which had been created to overcome defects of previously used devices, brought along with the intended removal of the defects in question new disadvantages, which in turn made it impossible to achieve the goal of optimal varnish coatings in every respect.
- a roller was used as the application roller in the device of the type mentioned at the beginning in CH-PS 624,591, the peripheral dumbbell surface of which has a concave curvature in the central part and an essentially curved portion in the lateral support edges for supporting the can body on the application roller of the can body had an adapted convex curvature (CH-PS 624.591, Claim 7 and S.3, r.Sp., Z.31-35).
- the middle part of the application roll extended from the middle of the roll to each of the two roll sides with a constant concave curvature up to a kink of the surface line representing the roll profile of the application roll, at which the middle part adjoins the convex edge area assigned to the relevant roll side and forming the supporting edge ( CH-PS 624,591, Fig. 5,6,8).
- This formation of the application roll was partly due to the special design of the stripping device and the above-mentioned shape of the stripper, which can be changed for the selectability of the profile of the lacquer layer applied to the weld seam (CH-PS 624.591, p.3, r.p. , Z.19-29, and Fig.
- 4,361,113 have apparently not succeeded in layer thicknesses of the lacquer coating over the weld seam in the optimal order of magnitude, So from above. 30 to 60 microns to achieve, but that with this application roller apparently only relatively thick lacquer coatings with a layer thickness of more than 150 microns can be applied.
- the invention was therefore based on the object of providing a device of the type mentioned at the outset which is suitable for providing the seams of canned hulls with a varnish coating which is optimal in all respects and which meets all the requirements which arise in the further processing of the can hulls and the later use of the cans such as crack resistance during flaring, resistance to aggressive filling goods, exclusion of gas inclusions in the paint as well as between paint and base and firm adhesion of the paint to the base.
- the application roll has at least one recess in a central region of its central part with a region width below 60% of the width of the central part, and the peripheral surface line in this central region has at least one kink point and / or has at least two turning points.
- the main advantage of the present device is that with it the optimal layer thicknesses of the lacquer coating over the welding or soldered seam can be obtained without difficulty len, which are neither too low for the stresses that occur during long-term storage of aggressive filling goods, nor too large for the tensile strength stress that occurs when the edges of the can bodies are flanged and, in the case of large layer thicknesses, is above the tear strength of the paint.
- Another significant advantage of the present device is that the formation of the application roller automatically results in a profile of the applied lacquer layer, which with the greatest layer thickness immediately above the weld or soldered seam and the continuously decreasing layer thickness after the edges of the lacquer coating is too precise meets the requirements that have to be met for an optimal coating due to the existing stresses.
- the application roll can advantageously be designed such that the central region of the central part thereof has a width of at least 5%, preferably more than 15%, and expediently at most 50% of the width of the central part of the application roll, and that the central part of the Application roll has a width of at least 72%, preferably more than 80%, of the roll width.
- the best results with regard to the formation of the lacquer coating can be achieved within these design limits.
- the deepest point of the depression expediently from a middle line running between the highest and lowest point of the peripheral surface line parallel to the roll axis, which divides the section of the surface line belonging to the middle part of the application roll into sections located above and below the middle line in such a way that that between the surface line and areas lying on the middle straight line above and below the middle line are of equal size, should have a greater distance than 0.775 times, preferably more than 0.82 times, the distance of the highest point of the peripheral surface line from the middle line.
- This minimum depth of the recess is necessary, apart from exceptional cases, in order to be able to apply enough coating compound to form a protective layer with a sufficient layer thickness on the welded or soldered seam area on the inside of the can body.
- the deepest point of the depression should therefore advantageously be at least twice as large, preferably more than four times as large, from the central straight line as the highest point of the peripheral surface line.
- the application roll has only one recess in the central area of its central part.
- the application roll can advantageously be designed such that the peripheral surface line in the central region of the central part of the application roll has at least one kink point, preferably located in the middle of the central region, representing an inner edge in the peripheral lateral surface of the application roll, and / or two preferably symmetrically to the center of the middle turning point and / or two at the outer ends of the middle area and preferably also symmetrical to the center thereof, each having an outer edge in the peripheral surface of the applicator roll representing.
- the peripheral surface line in the central region of the central part of the application roll can have at least one kink point representing an obtuse-angled inner edge in the peripheral surface of the application roll.
- the depression lies between two elevations located within the central region of the central part of the application roll, preferably at least approximately up to the can body.
- the application roll can expediently be designed such that the peripheral surface line in the central region of the central part of the application roll has at least one kink point, preferably located in the middle of the central region, representing an inner edge in the peripheral lateral surface of the application roll and / or two in the region of the depression and preferably turning points located symmetrically to the center of the middle area and / or at least two in the tip area of the elevations and preferably also located symmetrically to the center of the middle area, each having an outer edge in the peripheral lateral surface of the application roller and / or two outside the area of the depression and preferably also turning points located symmetrically to the center of the central area and / or two outside the area of the depression and preferably at the outer ends of the central area and preferably also symmetrical to the center it has kink points, each of which represents an inner edge
- the peripheral surface line at the deepest point of the depression can be particularly advantageous in that it has an obtuse-angled inner edge in the peripheral surface of the opening have support roller representative kink.
- the special advantage of this first variant of the basic shape is that it is possible with this variant to apply can coating with different coating diameters to one and the same application roller by applying pressure rollers arranged on the outside of the can body not only to the supporting edges of the application roller but also press on the two projections provided on the same, and the space between the peripheral jacket surface in the middle part of the application roller and the inner wall of the can body remains approximately the same size when the diameter of the manufactured can bodies is changed.
- the application roller has two depressions in the central region of its central part and an elevation located between them, preferably at least approximately up to the can body.
- the application roll can expediently be designed such that the peripheral surface line in the central area of the central part of the application roll has at least one kink point, preferably located in the middle of the central area, representing an outer edge in the peripheral lateral surface of the application roll and / or two in the area of the elevation and preferably turning points located symmetrically to the center of the central region and / or at least two in the region of the base of the depressions and preferably also located symmetrically to the center of the central area, each representing an inner edge in the peripheral lateral surface of the application roll and / or two outside of the area of the elevation and preferably also located symmetrically to the center of the central area and / or two outside of the area of the Raised and preferably at the outer ends of the central region and preferably also symmetrical to the center of the same, each having an outer edge in
- the peripheral surface line can each have an inflection point representing an acute-angled inner edge in the peripheral edge surface of the application roller at the deepest points of the depressions.
- the application roll can advantageously also be designed such that the peripheral surface line has an at least approximately circular convex course with a preferably larger radius of curvature, at least in the major part of its sections lying between the central region of the central part of the application roll and the outer ends of the central part than half the inside diameter of the can body.
- the radius of curvature of the circular course should expediently be between 1.25 times and 5 times half the inner diameter of the can body.
- the lateral support edges serving to support the can body on the application roll are expediently increased in relation to the outer ends of the central part of the application roll and preferably border with an obtuse-angled outer edge to the assigned roll side and over each an acute-angled outer edge to the middle part of the application roll.
- the raised support edges have the advantage that they bring about a relatively sharp delimitation of the outer edges of the protective shrouds or essentially exclude edge smearing. They are mainly provided when the distance of the peripheral surface line from the inside of the can body resting on the supporting edges from the outer ends of the central part of the applicator roll increases relatively weakly towards the central region of the central part.
- the supporting edges are located lower than the outer ends of the central part of the application roller and preferably with an obtuse angle Adjacent the outer edge to the assigned roll side and with an obtuse-angled outer edge to the middle part of the application roll.
- the peripheral surface line in the regions of the supporting edges which serve to support the can body has a convex curvature with a preferably at least approximately half Has inside radius of the can body corresponding radius of curvature.
- the present device can be particularly advantageous be further developed in such a way that to influence the layer thickness of the protective layer which forms after the application of the coating composition under the influence of the surface tension of the coating composition, means for cooling the welded or soldered seam area of the can bodies before the application of the coating composition and thus influencing the heating of the applied composition Coating mass through the heated welding or soldered seam area of the can body and thus to influence the surface tension of the applied coating mass are provided, preferably in the form of means for producing a cooling air flow directed from the outside towards the welding or soldering area of the can body.
- This has the advantage that the layer thickness of the protective layer can be adapted to the requirements placed on the protective layer within a specific layer thickness range which is essentially predetermined by the formation of the peripheral lateral surface of the application roller.
- lacquer flag 3 or 4
- the shape, size and stability of which primarily determine the properties of the lacquer layer that forms, so to speak the end of the lacquer flag that runs out on the inside of the can body and covers the weld seam area.
- the actual paint application takes place for the most part via this paint flag, or more precisely that the main part of the total amount of paint transferred from the application roller 2 to the inside of the can body 1 is not as previously assumed, for example at the time of contact between the application roller and Inside the can body but rather only afterwards is applied to the inside of the can body using this paint flag.
- the application process takes place in such a way that the inside of the can body is roughly at the point of contact between the application roller and the inside of the can body te is wetted with lacquer and this initially still thin wetting layer adhering firmly to the metal surfaces on the inside of the can body then pulls the lacquer carried by the application roller off the application roller via the lacquer flag.
- the front of the paint flag has - as indicated by the examples of paint flags 3 and 4 in Figures 10 and 11 - essentially the shape of a hyperbola, the asymptotes of which with a straight line parallel to the axis of the can body on the inside of the can body and a tangent to the application roll at the exit point of the
- the center of the paint flag on the applicator roller coincide and whose eccentricity, which is a measure of the paint flag length, is determined in the stable state of the paint flag by the surface tension and the toughness of the paint, and by the surface curvatures of the paint flag, especially at the apex of the hyperbola.
- the amount of the paint applied to the inside of the can body is essentially proportional to the volume of the paint flag and the geometric location of the largest coat of paint is the branch facing the inside of the can body of the hyperbole forming the front of the painted tab, or more precisely the outlet of this hyperload on the inside of the can body .
- the size of the paint flag In order to be able to keep the volume of a paint flag within a certain volume range, the size of the paint flag must be kept essentially constant, and this can only be achieved if the paint flag, when it is created, also achieves a shape with which this size is reached a stable state in the sense of a mutual all forces acting on the paint flag.
- the forces acting on a paint color are now essentially the forces caused by the movement of the can body and the rotation of the application roller and transferred to the paint flag by the toughness of the paint, in the sense of an extension of the paint flag and by the surface tension of the paint and the Forces caused by curvature of the surface of the paint flag, of which the forces caused by the convex curvature of the hyperbolic front of the paint flag act in the sense of an extension of the paint flag and the forces caused by the concave curvature of the paint flag cross section act in the sense of shortening the paint flag.
- the concave curvature of the paint flag cross section at the apex of said hyperbola must be so large that the forces caused thereby, in the sense of shortening the paint flag, act in the sense an extension of the paint flag acting forces, i.e. the forces caused by the movement of the can body and application roller and transferred to the paint flag by the viscosity of the paint and the forces caused by the convex curvature of the hyperbolic front of the paint flag, i.e.
- the paint flag must be with them Forms simultaneously with the achievement of the specified size, a shape with the size required for the balance of forces reach the concave curvature of the lacquer flag cross-section at the apex of the hyperbola forming the lacquer flag front, so that a stable state is established, and since the shape of the lacquer flag and in particular the width of the flag front determining the size of the concave curvature of the lacquer flag cross-section in the flag front vertex essentially depends on the formation of the peripheral lateral surface of the Depending on the application roll, the volume of a paint flag can only be kept within a certain volume range when using an application roll with a suitably designed peripheral jacket surface and accordingly only achieve a certain desired profile of the coating over the weld seam area with a suitable application roll.
- the peripheral surface line of the application roll or its distance from the roll axis should have at least two relatively close to each other and expediently approximately equal maxima in the middle part of the application roll. In a central area of the middle part of the application roll, at the outer limits of which or within these maxima, there must be at least one depression of the peripheral surface of the application roll or at least a minimum of the distance of the peripheral surface line of the application roll from the roll axis.
- the two maxima closest to the outer limits of the central region of the middle part of the application roll or coinciding therewith in the direction of the outer ends of the middle part of the application roll must also be part of the peripheral lateral surface of the application roll Connect the ren ends of the middle part to the decreasing distance of the peripheral surface line of the application roll from the roll axle.
- the distance of the peripheral surface line of the application roll from the The roller axis is expediently to be smaller than at the associated maximum and larger than or at least as large as at the assigned outer end of the middle part of the application roll and preferably to increase continuously from each of the two outer ends of the middle part after the assigned nearest maximum. This training promotes the desired movement of the paint in the direction of the two maxima.
- the peripheral surface line of the application roll should expediently have smaller distances from the roll axis than at the two maxima closest to the outer limits of the middle area of the application roll or coinciding therewith.
- the points in the support edge areas with the greatest distance from the roller axis should suitably only a little have a larger and advantageously at least almost the same distance from the roller axis as the outer ends of the central part of the application roller. This configuration can prevent paint flags from forming on the supporting edges.
- the maxima mentioned in the middle area or at the outer limits thereof should be sufficiently pronounced to enable or promote the formation of the desired paint flags at these points What a certain minimum depth or a certain minimum volume of the depression requires, but that on the other hand the lacquer volume within the depression and thus also the volume or depth of the depression must not be too large, so that the resulting paint colors do not come from the inside the volume of paint flowing in from the recess is pushed apart but rather pushed together by the volume of paint flowing in from the outside, so that they merge in the desired manner into a single paint flag.
- the depth of the depressions 10 or 10 'and 10 "compared to the maxima 7 and 8 is approximately in the application rollers with relatively wide depressions in Figures 1, 3 and 4 0.2 mm, in the case of application rolls with somewhat narrower depressions in FIGS. 2, 6 and 8, approximately 0.4 mm and in the case of application rolls which are provided with elevations in the central region 9 of the middle part 6 that reach up to the inside of the can body,
- the distance between the maxima 7 and 8 from the inside of the can body is approximately 0.3 mm for all application rolls shown in FIGS. 1 to 4 and 6 to 8.
- lacquer coatings could be applied over the weld seam area with a layer thickness over the weld seam of up to approximately 60 microns. Even larger layer thicknesses of up to 80 or 100 microns can be achieved with the application rollers in FIGS. 5 and 7, but there is generally no great need for layer thicknesses above 60 microns.
- the distribution of the layer thickness in the transverse direction of the coating can still be influenced to a certain extent by more or less strong cooling of the can bodies on their way from the welding station to the painting device by means of a cooling air flow directed from outside to the weld seam of the can bodies, since the applied paint is from the not yet cooled weld seam is heated and the surface tension of the varnish decreases with increasing warming, so that strong cooling of the can bodies can achieve a high surface tension of the applied varnish, which tries to pull the varnish surface smooth and thereby to some extent to compensate for the Layer thicknesses in the immediate vicinity of the weld seam ensures.
- FIG. 9 An example of a lacquer coating that was applied with the application roller shown in FIG. 1 is shown in cross section in FIG. 9.
- the lacquer coating was applied to the weld seam on the inside of a can body made of 0.2 mm thick sheet metal.
- the application roll used had a width of 10 mm and a peripheral surface line as in FIG.
- the present device for applying a protective layer to the welded or soldered seam of can bodies, apart from the application roll can be constructed in the same way as is described, for example, in OH-PS 624,591 or US Pat. No. 4,361,113 , ie an application roll according to the present invention can be easily used in such a known device and leads in connection with such a known device to the success achieved with the present invention. It is unnecessary is therefore a further detailed explanation of the structure and operation of these known devices in connection with the present invention.
- the up t ragsrollen according to the present invention corresponding to the given already in the CH-PS 624 591 excitation (p.3, r.Sp., Z.49-51) with a next to the application roller arranged Kotor, expediently to drive an electric motor.
- the stripping device provided for stripping the paint should be expediently designed such that, in the application rollers according to the present invention, the paint is completely stripped from the support edges 14 (which can be achieved by a scraper lying almost on the support edges 14), so that each Possibility of forming paint flags on the support edges 14 to be excluded.
